Tire Safety – Benefits of Temperature & Pressure Monitoring

Tire Safety – Benefits of Temperature & Pressure Monitoring

Tires play a critical role in the handling, maneuvering and braking of any motor vehicle. No matter what the type…RV, SUV, utility vehicle or commercial truck, tires are the only thing that contacts the road. Obviously, there is much more than just the vehicle resting  צמיגים    on those tires, its overall safe operation is as well. By following some basic tire safety practices, you will not only drive with a greater degree of security, you will extend the usable life of your tire investment considerably.

Tire Manufacturers Agree

It is commonly agreed that a primary cause of early tire breakdown and poor tread life is under-inflation. Low tire pressure not only causes excessive heat build-up in the tire, creating dangerous driving conditions, but also shortens tire life. Unwanted heat will rapidly increase tread-wear and can even tear down retreads and destroy tire casings. As much as 90% of all tire breakdowns is the direct result of tire under-inflation

The Low Pressure Problem

Under-inflation of tires is a serious safety concern because it forces excessive flexing on the sidewalls. This additional strain on the tire can build up more internal heat, resulting in the aforementioned hazards and premature tire failure. Research completed by the U.S. National Traffic and Safety Administration shows that one in three cars or light trucks are being driven with at least one significantly under-inflated tire. These improperly inflated tires wear out more quickly because they put more drag on the road (rolling resistance). This also leads to a reduction in fuel economy, something most individuals and fleet owners definitely want to avoid.

Pressure Influences Tread Wear

Maintaining proper tire pressure levels improves tread mileage as indicated below:

· A continuous 10% over-inflation reduces tread wear by 5%

· Tire Life will be reduced by 30% if constantly under-inflated by 20%

· For every 10 PSI (pounds per square inch) under-inflated, fuel consumption is increased 0.5%

· A continuous 20% under-inflation decreases tread wear by 25% By example, consider at an average price of a $250, a 20% under-inflated commercial truck or RV tire costs about $50 each in lost usage. Add in the costs of downtime, repairs and service fees; the picture becomes even clearer.

Fuel Efficiency Impact

Tire inflation also has a direct impact on fuel efficiency, since under-inflated tires can consume a greater percentage of each gallon of fuel just because of rolling resistance. The US Department of Energy advises that tires can account for as much as a 3.3% difference in fuel efficiency. The Department of Transportation’s (D.O.T.) studies have shown that the United States could save over 4.2 million gallons of fuel per day… just by keeping tires properly inflated!

Managing Fleet Maintenance Costs

Tires can account for as much as 36% of a vehicle’s maintenance cost. Yet this essential maintenance procedure, of regularly checking tire pressure, is one of the most difficult to enforce. Even the best preventive maintenance programs will discover truck drivers and even maintenance personnel will often short cut this time consuming procedure. In certain cases some tires are skipped, assuming if a few are good, the rest are as well. In other cases, this extremely important procedure is ignored entirely. With tires usually being the highest maintenance expense, can any fleet afford to ignore the direct cost consequence of poorly maintained tires?
